How Much Does it Cost to Replace and Install a Bathtub?

Bathtub Installation or Replacement Cost

The average cost to install a bathtub is $7,028, but can range from $4,096 and $10,541, depending on the type of tub and modifications needed. The average cost of the tub itself ranges from $200 to $8,500 or more.

Adding a new tub or replacing an existing one can help you create a spa-like experience for your entire bathroom. However, this project can also be time-consuming and labor-intensive. Unless you’re a skilled carpenter and plumber, it’s probably in your best interest to hire a professional to do the job. Here’s what costs to expect when planning a bathtub installation or replacement project.

Cost to Install a Bathtub

The cost to install a new bathtub ranges from $100 to $2,000. The most basic service includes setting and fastening. If you need to put in a waterproof layer on the wall or a new plumbing line, you’ll pay more.

Although the biggest price variable is the bathtub itself, it’s important to consider other factors like the condition of the existing plumbing or the installation surface. If you’re hoping to save the existing surround, be sure to find out if it’s even possible.

Installation Labor Costs

The cost to install a new tub runs from $100 to $2,000. Installation labor costs include prep work and installation. Basic surface preparation entails leveling the new tub's surface and adding in any necessary supports. Next, the new tub is installed and secured.

Depending on your contractor, cleanup may be included with your project fee, or it may be separate.

Average Cost to Replace a Bathtub and Surround

The average cost to replace a bathtub and surround is $1,500 to $11,000. Installation tends to run the least if you choose a combo with built-in shower and surround.

Cost to Tile a Tub Surround

The cost to tile a tub surround ranges from $750 to $1,500. This depends mostly on the material, which runs $0.50 to $15 per square foot. You’ll pay more for natural stone and less for ceramic.

Additional Cost Factors

Bathtub installation may require additional services, such as:

• Cost to replace a water heater: $800–$1,600

• Price to replace plumbing: $400–$1,900

• Cost to upgrade electrical panel: $500–$1,800

For example, if you double the size of your tub, you may need a bigger water heater or a new electrical panel to handle the jets.

Bath Liner

Bath liners fit over existing bathtub installations. Bathtub liner prices vary based on what type of material you choose (vinyl or acrylic), your bathtub’s size, and any design features (bathtub front), faucets and hardware, doors, and accessories. The average cost for a bathtub liner installation ranges from $2,100 to $7,700. 

Floor Reinforcements 

Floor reinforcements for bathtubs include floor joists and framing to help distribute and support the weight of a standard bathtub. A regular bathtub should be able to hold 40 to 60 gallons of water plus the weight of an adult. During installation, a bathtub pro will take into account the material and dimensions of your tub and ensure that it has adequate support underneath to hold the new bathtub. Preparing the surface may account for an additional $300 to $800 in project cost.

Shower-to-Tub Conversion Cost

The cost to convert a shower to a bathtub ranges from $1,900 to $10,400. The biggest factor is the price of the materials.

This range assumes that you don’t need to adjust the size of the space to make room for the tub. If you’re expanding your bathroom, you can expect to pay at least $10,000 to $15,000 more.

Bathtub Sizes, Styles, Prices, and Installation Costs

Most bathtub prices range from $600 to $14,000. The total depends mostly on the features and the size.

Jet & Whirlpool Tub Costs

The total cost to install a jetted whirlpool bathtub ranges between $1,500 and $17,000 with an average price of $6,500. This price includes the cost of the tub itself as well as installation charges and materials.

Labor typically costs $450 to $2,000, not including extra work like hanging new walls or pouring a concrete slab. The project takes an average of 18 hours to complete, with a total range of 6 to 25 hours.

*Joists and a concrete slab are not required for all installations.

Installation requirements of a standard jetted bathtub include materials like:

• Joists to strengthen the floor

• Glue and sealant

• Concrete to create an even surface

• Wires and parts to connect to the home's electrical system

Not all installations need joists and a concrete slab, but almost all require glue, sealant, and hookups to electrical systems. A full bathroom remodel may be required to handle the extra weight of the tub. The area surrounding the tub will also need to become fully sealed to prevent leaks.

When seeking to install a jetted indoor or outdoor tub, it’s best to start with hiring a plumber. In most cases, you’ll need to hire a plumber and a bathroom remodeler. A standard contractor is unlikely to have experience in all of these areas.

Cost to Install Jetted Bathtub vs. Whirlpool Hot Tub

The average cost to install a jetted bathtub falls between $1,500 and $17,000 while whirlpool hot tub installation costs between $1,250 and $10,700. The primary difference is in the cost of the tubs themselves, though hot tubs take less to install.

Soaking Tub Cost

The price of a soaking tub averages $1,000, with a range of $600 to $13,000. The cost depends mostly on the size since this type frequently comes large enough for two.

Soaking tubs can be drop-in or freestanding. Since they’re built for sinking in deep, the basin is usually at least 14 inches tall.

Cost of Freestanding Tub

The cost of a freestanding tub is $750 to $12,000, averaging around $2,500. This style allows for free movement on all sides. It usually requires a larger bathroom.

Garden tub prices range from $900 to $5,000. This type is freestanding and tends to be larger than average.

Walk-In Tubs

Walk-in tubs range from $2,000 to $8,000, about $5,000 on average. The price point depends mostly on the features, like jets.

A new tub costs $200 to $14,000, depending on the material. Most options range from $500 to $2,000.

Cast Iron Tub Cost

Acrylic

The cost of an acrylic bathtub ranges from $300 to $14,000. You can expect to pay $700 to $1,000 for most standard-size models.

Acrylic is generally resistant to abrasion and fading, which is why it’s popular for families. The non-porous finish makes it easy to clean and warm to the touch.

Cultured Marble

A cultured marble bathtub will cost between $2,000 and $5,000, installed. Labor will make up about $450 to $2,000 of this total. There are many options for materials when replacing your bathtub.

Cultured marble provides a sleek and stylish look, but it can also be brittle and scratch easily. It’s also considerably heavier than acrylic, which can be problematic if your floor cannot handle the additional weight.

Enameled Steel

Enameled steel bathtubs cost $200 to $1,000. This material is less expensive and lighter than cast iron. It also chips easily and may create a lot of noise when filled.

Fiberglass

The price of a fiberglass bathtub ranges from $200 to $800 for most models. This lightweight material comes in a range of colors. Since it does not retain heat well, it’s better for quick baths than long soaks.

DIY Tub Installation vs. Hire a Pro

Bathtub installation usually isn’t a DIY project, especially if you have to remove the old one. When you’re ready to find bathroom remodelers near you, remember to ask about past projects and get at least three quotes before you make a choice.
